Answer:
False, counterexample below
Step-by-step explanation:
Denote the unit vectors of R^3 by . Now consider
and
. We have that
. Also, the vector
is not a linear combination of
because any linear combination of these two vectors will have third coordinate zero, but v_3 has third coordinate 1 so they can't be equal.
However, the set is not linearly independent, because
is a non-trivial linear combination of these vectors that equals zero.
Answer:
21
Step-by-step explanation:
Three raise to third power can be written as . In this three is the base which is raised to third power.
Next we need to subtract 6 from Three raise to third power(i.e from 27)
which can be written mathematically as
Hence 6 less than three raised to the third power is 21 as explained above.
